Then, as shown in Figure 5 and Figure 6, on described grid 202 and gate line 201, form gate insulator 203 and semiconductor active layer 204 successively.
Then, as shown in Figure 7, on described array base palte 200 form data lines 205, drain electrode 206 and with the source electrode 207 of data line 202 one, described drain electrode 206 and source electrode 207 parts snap on the described semiconductor active layer 204.The periodically variable broken line of described data line 205 for extending transversely.
Then, as shown in Figure 8, form the pixel electrode 208 that is connected with described drain electrode 206 at described array base palte 200.
As shown in Figure 9, Fig. 9 is the partial enlarged drawing of Fig. 8, and by a plurality of pixel cells 208 that described data line 205 and described gate line 201 limit, each pixel cell 208 comprises laterally adjacent first sub-pixel 209 and second sub-pixel 210.Described first sub-pixel 209 and second son roughly are trapezoidal as 210 elements, and described first sub-pixel 209 and second sub-pixel 210 are the reversal dip layout.Described first sub-pixel 209 and second sub-pixel 210 have a pixel electrode separately.
Continuation is with reference to figure 9, and the data line 205 in described each cycle comprises first's data line 2051 of favouring horizontal direction and is connected also reversal dip with described first data line 2051 in the second portion data line 2052 of horizontal direction.In the present embodiment, described first data line 2051 is straight line, described second portion data line 2052 broken lines.Need to prove, for ease of explanation, with 2051 overstrikings of first's data line, second portion data line 2052 is attenuated among Fig. 9 that distinguish mutually with this and other data line, but those skilled in the art should know, described data line 205 can wait thick.First's data line 2051 of a corresponding data line is straight line in the pixel cell 208, the second portion data line 2052 of a described data line is broken line, first's data line 2051 of another corresponding data line is broken line in the described pixel cell 208, and the second portion data line 2052 of described another data line is straight line.Certainly, also described first data line 2051 can be set to broken line, and described second portion data line 2052 is set to straight line.
In Fig. 9, have only pixel electrode 208 zones to be only effective viewing area, other zones all can adopt the shading means to be blocked when showing, belong to invalid viewing area, and the area that fully improves effective viewing area is the main method that improves aperture opening ratio.In the present embodiment, the vertically thin film transistor (TFT) of first sub-pixel 209 between the adjacent pixel unit 208 setting of oppositely or relatively staggering, the setting of staggering relatively or oppositely of the thin film transistor (TFT) of second sub-pixel 210.Adopt the structure that arranges of described first data line 2051 and second portion data line 2052, can fully enlarge the region area of pixel electrode 208, therefore can effectively improve the aperture opening ratio of described array base palte 200.Should be understood that, do not requiring under the occasion of aperture opening ratio, also each sub-pixel proper alignment in order all can be set to straight line with described first data line 2051 and second portion data line 2052.
Then, form dielectric layer (not shown) at described pixel electrode 208; And forming public electrode at described dielectric layer, preferred, described public electrode is broach shape electrode.
Then, as shown in figure 10, provide a color membrane substrates 300, at the one side formation lens arra 301 of described color membrane substrates 300; Another side at described color membrane substrates 300 forms colored filter 302 and black matrix 303.Described colored filter 302 comprises Red lightscreening plate (R), green color filter (G) and blue color filter (B).Described colored filter 302 also comprises the colored light-filtering units 304 corresponding to pixel cell 208 on the described array base palte 200, and described colored light-filtering units 304 also comprises corresponding to the first sub-colorized optical filtering pixel 305 of first sub-pixel 209 on the described array base palte 200 with corresponding to the second sub-colorized optical filtering pixel 306 of second sub-pixel 210.The first sub-colorized optical filtering pixel 305 of described second sub-pixel 210 is with a kind of colored filter.Wherein, the width L1 of each lens is less than or equal to the cross-sectional width L2 of described pixel cell along continuous straight runs in the described lens arra 301, and described lens arra is along transversely arranged.
Then, described array base palte 200 and color membrane substrates 300 are fitted mutually, and at the space filling liquid crystal that is formed by array base palte 200 and color membrane substrates 300, form bore hole 3D liquid crystal indicator.Because, the periodically variable broken line that described gate line 202 is set to extend longitudinally, light blocks through described gate line 202, because described gate line 202 is broken line, therefore in whole gate line 202 zones, the gate line of broken line shape is compared with the gate line of rectilinear form, formed some groups different, with the periodic structure of lens the periodic structure of certain angle arranged, thereby can weaken Morie fringe.As shown in figure 11, eye-observation to the uneven degree of Moire fringe lighten.
The generation of Morie fringe be because the cycle of the cycle of the data line of arranging with the same direction of lens arra or gate line and lens arra identical or close.Therefore and the Morie fringe that produces all can weaken after adopting broken line to arrange to the data line arranged along the lens arra orientation or gate line.Should be understood that, after as long as the data line that will arrange along the lens arra orientation or gate line adopt broken line to arrange, just can reach the effect that weakens Morie fringe, but in order to improve the aperture opening ratio of array base palte, also data line and gate line all can be set to periodically variable broken line.
